Title: Improvements in and relating to machines for shelling rice and other hard kernelled grains, seeds and beans
IPC: B02B3/04
Filed: 1938-06-16
Abstract: 515,325. Hulling rice &c. BROWN, R. H., and MOULSDALE & CO., Ltd., W. E. June 16, 1938, No. 17937. [Class 58] Rice, and similar grains are shelled by passing between a hard toothed shelling roller and an endless band of resilient material running over rollers. The common plane in which the axes of the shelling roller and the main supporting roller of the band lie being inclined with respect to the band so that the grains pass below the shelling roller before the band reaches contact with the supporting roller. The rice is fed into a box 3 which delivers it on to a preferably longitudinally grooved feed plate 4 over which a coarsely corrugated roller 5 rotates to check the flow and to maintain a single layer of grains over the full width of the feed plate. The grains pass on to a slow running endless band 6 of resilient material passing over rollers 7, 8, the roller 8 being adjustably mounted. A fast running hard shelling roller 9, provided with teeth arranged parallel or slightly inclined to its axis is mounted above the belt so as to engage and hull. the grains thereon just before, the belt engages the supporting or anvil roller 7. The roller 9 may be vertically adjustable and also adjustable horizontally with reference to the anvil roller; this latter adjustment may be made while the machine is running. The small kernels are shot by the roller 9 against a deflecting plate 10 and apron 11 past an adjustable divider board 12 into a shoot 13 the lighter and rougher upper husks and also the lower husks resting on the band 6 falling into a shoot 14, A transverse air current is preferably directed across the falling material to a conduit 16 to ensure the separation of husks and kernels, the velocity of the current being made high if it is desired to carry away the husks in it. The grooves in the shelling roller are such that the grain lies wholly within the groove and that pressure is applied to the grain only from the floor of the groove. Specification 439,399 is referred to.

Title: Improvements in or relating to methods of forming adherent layers of powdered material on supporting surfaces
IPC: H01J9/22
Filed: 1952-07-16
Abstract: A support, e.g. the screen of a cathode ray tube, is provided with an adherent layer of powdered material by settling the latter on to the surface through a liquid containing an electrolyte in solution, and a solution of a binder-forming material is then added to the supernatant settling liquid without disturbing the powder layer, e.g. by spraying it on the surface of the settling liquid, or injecting it beneath the surface thereof, the solution of binderforming material being such that, with or without chemical reaction with the electrolyte, a binder dispersion is obtained in the settling liquid, and is allowed to precipitate on the powder layer before removal of the supernatant liquid.  The binder dispersion is a precipitable dispersion, preferably colloidal, capable of forming a gel, which acts as a binder, on the powder particles and supporting surface. The electrolyte may be capable of reacting with the binder-forming material to form the binder dispersion in situ in the settling liquid, and the solution of binder-forming material may contain the said material as the only solute, or both the binder-forming material and a precipitant therefor in such proportions as to produce at least part of the binder dispersion before addition to the settling fluid, the dispersion being stable except locally where it contacts the settled powder layer.  The powder may be a luminescent material, and the binder-forming material a water-soluble silicate.  The precipitant or electrolyte may be a normal salt of a monovalent or divalent cation which does not react adversely with the binder-forming material under the conditions used; barium nitrate, barium acetate, sodium sulphate and magnesium sulphate are mentioned. The settling liquid may alternatively or additionally contain an acid, e.g. phosphoric, or an acid salt or a salt behaving as an acid salt in aqueous solution.  If the precipitant is added to the solution of binder-forming material, the settling liquid may consist of incompletely de-ionized tap water.  After the usual washing the support surface may be treated to reduce electrical repulsion between it and the powder particles by washing with dilute acids, or with substances capable of imparting to it a positive charge, e.g. ferric salts, aluminium salts and cationic capillary active electrolytes such as "Lissolamine" (Registered Trade Mark), and rinsing with deionized water.

Title: Process for the removal of phenols from aqueous liquors
IPC: C07C37/00
Filed: 1935-06-24
Abstract: Phenols are removed or recovered from aqueous liquors containing them by subjecting said liquors to extraction with hydrogenated oils, such liquors being treated as do not form a homogeneous solution in the hydrogenated oils, and separating the two layers formed.  The phenols may be recovered from the solution in the oils in known manner, e.g. by washing out with alkali lye or by distillation, after which the hydrogenated oil may be used again.  Suitable hydrogenated oils are those obtainable by hydrogenation of tar oils, e.g. those produced by carbonization of bituminous coals, or of acid oils, such as are obtained in the dry distillation of the resins formed in the refining of crude benzol by means of sulphuric acid.  The process is applicable to the treatment of waste liquors containing phenols of any origin, e.g. from coke plants, coal tar distillation plants or brown coal low temperature distillation plants, and particularly to the treatment of aqueous waste liquors obtained in the destructive hydrogenation of coal and like distillable carbonaceous materials. In an example, waste water from the destructive hydrogenation of coal is stirred with an equal quantity of hydrogenated wash oil boiling at 220--350 DEG  C., and the upper layer is extracted with aqueous sodium hydroxide to obtain sodium phenolate.

Filed: 1938-06-20
Abstract: 517,374. Destructive-hydrogenation. ARMSTRONG, J. J. V. (Naamlooze Vennootschap Internationale Hydronge Neeringsoctrooien Maatschappij). June 20, 1938, No. 18213, [Class 32] Middle oils suitable for use as diesel oils are obtained from heavy oils and residues containing asphalts by treating the oils with hydrogen at temperatures between 450‹ and 550 ‹C. in the presence of catalysts, the activity of which lies below that of catalysts of standard hydrogenating activity (as defined in Specification 477,944) with a throughput adjusted above 0.5 kg. of initial materials per litre of reaction space per hour and under a hydrogen pressure adjusted within a range above 250 atmos. according to results obtained by preliminary experiments so that the asphalts (determined by the propane method) are reduced to a content of less than 6 per cent. and 30 to 70 per cent. of liquid products boiling up to 350‹C. (calculated on the final product) are newly formed. The pressures are preferably regulated in accordance with the propane-asphalt content so that for 8 per cent. asphalt the pressure is about 320 atmos and for 15, 33, 50, and 60 per cent. about 360, 450, 550 and 600 atmos respectively, and also in accordance with the quantity of residue obtained by distillation of the initial material up to 325‹C. under a pressure of 20mms. of mercury, e.g., pressures of the range set forth above are used with vacuum residues of 10, 15, 25, 35, and 40 per' cent. respectively. Where the pressures indicated differ in each case a value obtained from the average of the two pressures in question is used for the preliminary experiment. Catalysts having an activity below the standard hydrogenating activity are brown coal, small coke, active carbon, iron oxide, bleaching earth, silica gel, diatomaceous earth, magnesia and may be used with small quantities of oxides of other compounds of the metals of the 5th and 6th groups or with sulphates, e.g., nickel or iron sulphate. The reaction temperature should be maintained below that at which substantial dehydrogenation takes place by selecting temperatures so that the specific gravity of the fraction boiling above 325‹C. in the final products is not higher than the corresponding fraction in the initial material. In treating a cracking residue of an asphalt base oil containing 42 per cent. by volume of propane-asphalt and 6 per cent. of constituents boiling up to 325‹C. and which yields, when distilled up to 325‹C. under 20mm. pressure, 49 per cent. residue, in presence of a catalyst comprising 1 per cent. brown coal, small coke impregnated with iron sulphate the following comparative conditions and results of two experiments are given:- In experiment 2, double the quantity of catalyst was required.

Driving pumps; regulating pumps.-The output of a pump supplying fuel to an internal-combustion engine is maintained substantially constant irrespective of the engine speed. The pump 9 is driven from the engine cam-shaft 2 through bevel gearing 3, 5, shaft 4, friction disks 18, 19, 20, and shafts 7, 8. The driving-disk 18 is adjustable by the handle 12, which controls the carburettor throttle valve 14 in such a manner that, at maximum throttle openings, the disk 18 is at the edge of the disk 20, and that as the throttle is closed and the engine speed falls the disk is moved towards the centre so as to maintain the speed of the disk 20 constant. The axial movement of the disk 18 is less pronounced as it approaches the periphery of the disk 20. In a modification, the pump draws its supply from a tank below, and forces it to a tank above the level of the carburettor, which is fed therefrom.
